It does actually. The alcohols are mainly made from the carbon in CO2 and the hydrogen in H2O. Isobutanol is (CH3)2CHCH2OH, and isopropanol is C3H8O. So that's a lot of O left over.
Roughly speaking, energy + CO2 = carbon + oxygen. Left to right is photosynthesis. Right to left is fire.
[edit: do be careful when applying this equation in practice! Often, hitting CO2 with a big hammer just yields CO, or carbon monoxide. It's poisonous!]
